About the AirTAC GC300-08 FRL Unit (GC30008MNWK)
The GC30008MNWK is a genuine AirTAC three-piece F.R.L. combination - separate filter, regulator and lubricator - combining the W-code 5 um filter element with a fitted reverse/check valve (K) that holds downstream pressure through upstream dips. This size 300 set is threaded PT1/4 (PT is the standard; G and NPT are catalogue options), drains the filter bowl manually (M code), and has no pressure gauge fitted (N code). Maximum working pressure is 1.0 MPa (145 psi); operating range -5 to 70 C, non-freezing. At size 300, the filter and lubricator bowls are PC (polycarbonate).
The G-series offers sizes 200, 300, 400 and 600, ports from 1/8 to 1 inch, drain choices (differential-pressure, automatic or manual), 40 um or 5 um (W) filtration, gauge options with MPa, psi or bar scales, and the reverse/check valve (K) fitted here. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow curves for the GC30008MNWK on request.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.
Model Code: AirTAC GC300-08 FRL Unit (GC30008MNWK)
| GC300 | G-series F.R.L. combination, 300 body — sets the port range. |
|---|---|
| 08 | Port size PT1/4". This body offers 08 = PT1/4", 10 = PT3/8", 15 = PT1/2". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF300-08 filter, GR300-08 regulator and GL300-08 lubricator.
Size Class & How It Differs From GFC
- GC200PT1/8" - PT1/4"
- GC300PT1/4" - PT1/2"
- GC400PT3/8" - PT1/2"
- GC600PT3/4" - PT1"
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Where the AirTAC GC300-08 FRL Unit (GC30008MNWK) Is Used
Bottling Line Valve Stacks
Prepares air for filling and capping valve stacks, where the 5 um element protects fine pilot circuits and the check valve holds the regulated supply through filler stoppages.
High-Cycle Sorting Gates
Feeds diverter gates and sorting cylinders running thousands of cycles per shift, with fine filtration and held downstream pressure keeping valve response consistent.
Textile Machine Pneumatics
Conditions air for loom and winding machine pneumatics, where steady regulated, lubricated air and protection from supply dips support continuous multi-shift running.
Is the AirTAC GC300-08 FRL Unit (GC30008MNWK) the Right Station?
Step through sizes 200, 300, 400 or 600 and their ports (1/8 to 1 inch) against your air demand; this is size 300 at PT1/4. Drain: this unit is manual drain (M) - choose automatic (A) or differential-pressure (default) where bowls are not drained on schedule. Regulation range for this manual-drain set is 0.05-0.9 MPa (7-130 psi). The W code gives 5 um filtration, and K adds the reverse/check valve that keeps downstream pressure when upstream supply drops - the combination to specify for sensitive, high-cycle circuits. No gauge is fitted (N code); embedded square or external round gauges with MPa, psi or bar scales are options. Thread is PT as standard, with G (BSPP) and T (NPT) as catalogue options. Flow appears only as curves, not a single rating - ask us to confirm sizing against your application before ordering.
Quick checklist
- ✓ Body size for your peak flow (PT1/4" here)
- ✓ Element 40 µm or 5 µm
- ✓ Drain sets the regulating band
- ✓ Gauge fitted, shape and scale
- ✓ Three-unit (GC) or two-unit (GFC) layout
- ✓ Oil mist acceptable downstream
Installation & Maintenance Notes
- check Install with the airflow arrow: filter first, lubricator last.
- check Mount vertically, bowls down.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Adjust only within 0.05 - 0.9 MPa (7 - 130 psi).
- check Drain condensate before the bowl fills; check the oil level.
- check Keep the station above freezing (-5 to +70 °C, unfreeze).
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC GC300-08 FRL Unit (GC30008MNWK) FAQ
AirTAC publishes G-series flow as curves, not as a single rated figure, so no rated number is quoted here. Share your machine's air demand and working pressure, and we will confirm the GC30008MNWK datasheet and flow curve on request, then verify that size 300 at PT1/4 is correctly sized.
GC is a three-piece F.R.L.: separate filter, regulator and lubricator, so each section can be serviced or replaced on its own. GFC is a two-piece set that merges the filter and regulator into one body plus a lubricator. Both add lubrication; GC gives you the most flexibility, and both are offered in this same size 300, PT1/4 configuration.
